Claims

[Scope of utility model registration request]

A tubular horizontal rail 4 is attached to the horizontal rail mounting surface 2 of the column 1.
A tightening bolt 6 is inserted into the mounting holes 3 and 5 drilled in the contact surfaces of the support column 1 and the horizontal rail 4, respectively, so that one side of the tightening bolt 6 is in contact with the bolt body 7. The cylindrical body 8 is inserted through a cylindrical body 8 and a sleeve 9, and the cylindrical body 8 has a pedestal 10 protruding from one end on the head side of the bolt body 7, which is non-rotatably fitted into the mounting hole 3 of the column 1, and a pedestal 10 protruding from the other end. A tapered part 12 having a rotation stopper 11 is formed on the outer surface, a cut groove 14 is formed along the length direction from one end side of the sleeve 9 that comes into contact with the cylindrical body 8, and a bolt body 7 is formed on the inner surface of the other end. A threaded portion 16 is formed to engage with the bolt body 7, and when the bolt body 7 is tightened, the sleeve 9 is drawn toward the cylindrical body 8 and the sleeve 9 is expanded, so that the end of the sleeve 9 comes into contact with the inner wall of the horizontal rail 4. A mounting structure for a post and a horizontal rail in a protective fence in which a horizontal rail 4 is fixed to a post 1.
